Maui

An ancient hero who monitors the seas around Hawaii, Australia, and Aotearoa.

She fed the sealed beasts known as Zaratan, creatures which eat rocks on dragon veins, rocks from places that are not dragon veins, greatly reducing their danger.

She also informed the ancient heroes of the deliciousness of Zaratan, causing them to overfish it. Using such tricks, she was the first to exterminate a sealed beast without sealing it.

She realized that feeding ordinary crabs rocks that contain dragon vein energy will cause them to turn into Zaratans, and is currently working on cultivating Zaratans that are less dangerous.
